Postcodes / Zipcodes / 2013 95% open

What data is expected?

A database of postcodes/zipcodes and the corresponding geospatial locations in terms of a latitude and a longitude (or similar co-ordinates in an openly published national co-ordinate system). A database which gives a location in terms of the name of a town or a street without lat/long co-ordinates is not considered acceptable unless the name of the town or street can be further converted to a latitude and longitude by means of other open data (eg an open gazetteer with latitude and longitude attributes).

Details

The Isle of Man Government still owns the Isle of Man Post Office. Postcode searches require a registered email address (free) and rate limited to 10 searches per day.

The government IT department sells the postcode/geolocation dataset to a very small customer base of couriers, dairy co-operative doorstep milk delivery service, Tesco, etc.

An IT services company (http://www.afd.co.uk/) also resell geolocation datasets and data cleansing services.
